Interestingly, we had a similar problem when generating our help notebooks. 
With thousands of notebook files, we wanted to reduce space without 
fundamentally changing the notebook format or introducing intermediate
steps, so that customers could reasonably download a product image from
the Wolfram store with full documentation.

To resolve this, I created a method for converting cells to bitmaps 
conditionally based upon whether doing so would actually reduce the byte count 
of the file.  As a part of the documentation build process, this is applied to 
all output cells.  This means that some graphical output cells are not bitmaps 
(because the underlying expression was smaller than the bitmap), and also that 
some textual outputs are bitmaps (because the bitmap compressed even better than 
the textual representation).  Additionally, the conditional conversion will
refuse to convert any cell with a Dynamic[] inside of it, so that interfaces
will continue to function.

To invoke this functionality, do...

NotebookFind[InputNotebook[], "Output", All, CellStyle];
FrontEndTokenExecute[
 InputNotebook[], "SelectionConvert", "BitmapConditional"];
